The 5.9-liter Cummins 12V 6BT inline-six engine generally doesn’t have too many issues, even with its wiring and sensors. However, the throttle position sensor is prone to failure.

Make sure your sensors and wiring are in good working order. Find the right TPS, 5.9 Cummins IAT sensor, and more at ProSource Diesel.
